To all fwhom 'it may concern.' Y

Be it known that I, Isinon Emmen, a sublject of the Emperor of Germany, residing at Pforzheim,`in the Duchy of Baden, Germany, have invented certain new andusemprovements -in Bracelets; and I do hereby declare the .followin Vreference marked thereon, which form a part of this specification.

This inventionrelates fto new and useful improvements in endless chain bracelets so arranged that the chainwill expand under the influence of springsI and contract drawing the links back to their normal positions after the bracelet is sli ped over the hand and upon the wrist of t e wearer, and comprises lvarious details of construction, combinations and arrangements' of parts which will be Pnying hereinafter fully described, and then'speciiicallfdened in the appended claims. y invention -is ustrated in the accomdrawiii s, which, with the letters of reference marke thereon, form a part of this ap lication and in which i 'gure 1 is a side elevation of my im roved bracelet. Fi 2 is a sectional view t ough rigs andra ortion of a second link connected thereto. ig. 3 is va cross sectional view on line 3-3 of Fi 2. Fig. 4 is a sectional view on line -4-4' oFig.' 2,.

The ends 'of said tubular pinsare preferably clencheda ainst the marginal s edges. of the apertures in t e bars A, through by the previsioni of ja v Vmoved from the wristlad "-f rifinita im. se, isos.
